	Hi Stoyan, This question actually connected with another one (http://mindfusion.eu/Forum/YaBB.pl?num=1407499104). But I would have separated it. When I draw an additional labels, there is the same font style as for the node: Code var node = e.Node; ... diagram.DrawStyledText(e.Graphics, label, node, labelRect); I tried to create a new TextAttributes to use instead (I need a smaller font, in different color and not bold as node's text for this additional labels): Code var txtAttr = new TextAttributes(node) { FontSize = 7, FontStyle = System.Windows.FontStyles.Normal, TextBrush = new SolidColorBrush((Color)ColorConverter.ConvertFromString("#FF0070E0")) }; The problem is that FontSize works, but it does not affect the FontStyle and BrushColor. Can I define all this settings separately from the node's text style? Thanks, -Kostya

	Hi Kostya, DrawStyledText ignores font style and color attributes and instead applies respective attributes defined via HTML tags in the text. In order to use different styles and colors with DrawStyledText, add the formatting elements listed here to the labels: http://www.mindfusion.eu/onlinehelp/wpfdiagram/index.htm?CC_Text_Attributes_and_... Alternatively, instead of DrawStyledText you could render labels using DrawingContext.DrawText method to use specified TextAttributes values. E.g. create a FormattedText object like this: Code var typeface = new Typeface( textAttributes.FontFamily, textAttributes.FontStyle, textAttributes.FontWeight, textAttributes.FontStretch); var text = new FormattedText(label, System.Globalization.CultureInfo.CurrentCulture, FlowDirection.LeftToRight, typeface, textAttributes.FontSize, textAttributes.TextBrush); r.Graphics.DrawText(graphics, text, labelRect.Location); I hope that helps, Stoyan

	Hi Stoyan, Thanks much! I picked the DrawStyledText way, since it is shorter, and I suspect that the similar operations with the text occur in the background anyway. -Kostya
